Limits
Limit lines can be defined to compare the data to your defined limits and indicate a pass or
fail condition. Limits accesses menus that allow you to create, modify, and change the
properties of limit lines. There are two limit lines in the instrument.
Key Path: Display
State Saved: Not saved in instrument state.
Factory Default: Unaffected by system defaults.
Remote Command:
:CALCulate:LLINe[1]|2:DATA <x-axis>, <ampl>,
<connected>{,<x-axis>,<ampl>,<connected>}
:CALCulate:LLINe[1]|2:DATA?
Defines the limit line values, and erases all existing data. Up to 200 points may be defined
for each limit using the following parameters.
<x-axis> can be frequency or time values as specified by the following command:
:Calculate:LLINe:CONTrol:DOMain.
Frequencies are always in Hz. Time is always in seconds. No unit is allowed in this
parameter.
Range: − 30 Gs to +30 Gs for time limits, − 3 kHz to +350 GHz for frequency limits.
<ampl> amplitude values are always in units of dBm. Up to two amplitude values can be
provided for each x-axis value, by repeating <x-axis> in the data list. No unit is allowed in
this parameter.
Range: − 140 dBm to +100 dBm
<connected> connected values are either "0" or "1." A "1" means this point should be
connected to the previously defined point to define the limit line. A "0" means that it is a
point of discontinuity and is not connected to the preceding point. The connected value is
ignored for the first point.
:CALCulate:LLINe[1]|2:DATA:MERGe <x-axis>, <ampl>,
<connected>{,<x-axis>,<ampl>,<connected>}
Adds the points with the specified values to the current limit line, allowing you to merge
limit line data. Up to two amplitude values are allowed for each x value. If more than 200
points are entered to be merged, the first 200 points are merged into the existing limit, then
an error ‘too many DATA entries’ is reported.
